olive tint. Subcostal- vein of the fore wings parallel with the costal ; 
the three discoidal veins about equidistant at their bases; stigma 
fusiform, opaque, brown. 
Apterous female. Honey-tubes extending slightly beyond the tip of 
the abdomen, black ; tail white ; legs yellow, except the joints, which 
are dusky ; the femora are generally pale at the base. Antennae 
about as long as the body, marked as in the pupa, except that the 
light portions are clear white. Beak reaching nearly to the hind 
coxae. 
Pupa. Oval, width about two-thirds the length ; length about .05 
inch. Antennae nearly as long as the body ; first and second joints 
dusky, third and fourth bright yellow, apex dusky. Eyes black. 
Wing-pads greenish at the base. 
Found on the heads of Eetaria glauca and Panicum crus-corvi , 
Carbondale, Illinois, in August. 
It is possible that those found on Panicum belong to a different 
species, as the wingless specimens are of a lighter color, and have a 
distinct tubercle on the sides of the neck, which I failed to observe in 
those on Setaria. If it should appear that these are specifically dis- 
tinct, the species may be named & 'iphonophora panicola . 
8. Siphonophora euphorbiae, new sp. 
Notes in reference to color lost. If I remember rightly, it was green 
or greenish, similar in color to the following species, but distinct. 
Antennae longer than the body, very slender ; the third and seventh 
joints very long ; a few regularly placed hairs on them. Honey- tubes 
long and slender, reaching beyond the tip of the abdomen, nearly one- 
third as long as the body, cylindrical. Tail very distinct, ensiform and 
slender, about half the length of the honey-tubes. Subcostal vein of 
the front wings diverging as it leaves the base, so as to leave the 
widest space between it and the costal vein opposite the insertion of 
the first discoidal vein, then approaching and joining it at the stigma. 
Found at Sioux City, Iowa, September 1st, on Euphorbia maculata. 
The specific name euphorbiae has already been used in Aphis, but 
this being in a different genus, it will not create confusion. 
9. Siphonophora euphorbicola, new sp. 
Winged viviparous female . Antennae longer than the body ; 
general color pale pea-green ; honey-tubes long, extending beyond the 
tip of the abdomen, equal in length to about one-fourth of the body. 
Head pale glaucous, the two lateral ocelli distinct ; eyes dark ; 
antennae dusky, except the basal joints and base of the third joint, 
which are pale. Thorax with a slight purplish tint ; prothorax green ; 
abdomen pale green ; legs hyaline. Honey-tubes pale green at base, 
dusky at the tips; tail long, slender, sword-shaped, greenish. Veins 
of the wings slender and very straight, except the stigmatic, which is 
strongly curved. Beak reaches the hind coxae. Length to tip of 
abdomen .09 inch ; to tips of wings .15 inch.
